The Parisian club has now won the season-opening trophy on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown between the French league winners and the French Cup winners after the French winger found the net early on.
Yet, the southern French side fired twice late to seize a surprise advantage. First, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a vital equaliser in the final seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a convincing penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the past thirteen years.
